I'm not sure if this is relevant but I recently had my Juke serviced and since then my Bluetooth connection keeps dropping.  It happens 3 or 4 times during a half hour commute and each time it drops out for about 30 seconds.  I don't think it's my phone because it also does it with my husband's phone.  Has anyone else had this problem/? 

I cannot see how having it services would affect the bluetooth operation unless the battery was disconnected (say for battery or cambelt replacement).

Worth taking it into the dealer to ask them and they may have the answer or even an update they can upload into the audio system.
